I just want to give a HUGE ENDORSEMENT to Thomas Kurtz and his wonder SELF DEFENCE UMBRELLAS.
Floro Fighting Systems has been using Mr Kurz Umbrellas for more than a decade. It's a top quality tool with a great warranty and impeccable customer service.
Mr Kurz sent me some "Sparring" umbrellas to test out. They are HIGHLY RECOMMENDED!!!!

To make this "safer"; modification had to be made. I cut the shaft so only about 12 inches protrudes from the hook handle.
The foam is cut at 14 inches
The foam is attached to the end. Ensure that the pipe is not inserted flush to the tip. Leave a gap and fill than gap with foam.
It is important to "pat" down the gaff tape to the foam. Do not bind the body of the foam tightly.
